92 o2 wiring help
 

i dropped my exhaust but forgot to uplug the o2 sensor. the four wires coming from the ecu to the o2 plug pullde out. does anybody know which wire goes where? the wires on the o2 sensor itself is different in color so its not like i can just match up the colors. any help is greatly appreciated. or if someone has a wiring diagram with the color codes so i can plug the wires in the correct slot before plugging in the o2.

DIY section has a sticky-thread about on-line manuals. You should be able to find a shop manual for 90-92-ish Accord.
